OPERATING INSTRUCTIONS - 5
ELECTRONIC SPEED CONTROL (IF EQUIPPED)
This engine is equipped with a Digital Throttle Control
(DTC) system. The system uses a throttle cable
connected between the throttle handle and a Throttle
Control Positioning (TCP) sensor located on the engine.
The Throttle Control Positioning sensor provides throttle
position information to the engine management system
which, in turn, electronically controls engine throttle
movement.
This boat may also be equipped with an electronic
speed control system for skiing, wake boarding, or cruise
control. When the boat is operated in a speed control
mode, the operator
may not have full control of the
throttle until the speed control system is deactivated.
Example: If the speed control system is engaged at 32
mph, the throttle handle may be “dead” when trying to
accelerate above 32 mph. The speed control system
would need to be disengaged, then the operator will gain
full control of the boat speed.
Refer to your Boat Manufacturers Owners/Operation
manual for specifi c operation and troubleshooting
information for your speed control system.
ENGINE ALARM SYSTEM (OPTIONAL)
The PCM engine electronic system is programmed to
control the engine alarm system. This system utilizes
an indicator lamp (“MIL” or “Check Engine”) and/or an
optional audible alarm to warn the operator of possible
engine problems.
The alarm circuit has a “self” checking feature
programmed into the system. This feature will
momentarily light the “MIL”, and if equipped, sound the
alarm for two short pulses upon initial start-up of the
engine.
If the “MIL” lights and/or the alarm sounds during
operation, observe the instrument panel readings for
the possible source of the malfunction, such as low oil
pressure or excessive engine temperature readings.
Other conditions that may sound the warning buzzer are
a transmission over-temperature warning (if equipped),
exhaust gas over-temperature warning (if equipped), and
for an electronic throttle malfunction.
IMPORTANT: A failure involving the Electronic Throttle
may result in Idle only operation of the engine. The
operator must obtain service by an authorized PCM
dealer to determine the exact cause of this malfunction
as soon as possible.
In most cases, when the “MIL” light is on, the engine
may lose some performance and/or effi ciency, but
remain running adequately. Also, the light may go out or
become intermittent, but a trouble code will be logged for
future diagnosis.
In any case, the operator must obtain service by an
authorized PCM dealer to determine the exact cause of
the malfunction.
NOTICE: Some boat builders may install their own
alarm system. It is recommended that the boat owner
check with his or her boat dealer for an explanation of
the particular alarm system upon initial delivery.
